Quick & easy method to recharge your Jeep Quadra-Lift suspension system at home.
PARTS NEEDED:
• Nitrogen cylinder ($150 at local welding supply house, or just rent one.)
•CGA 580 regulator ($60 used on ebay)
•r134 AC charge hose ($15 @ AutoZone)
•Pneumatic hose & fittings/clamps ($20 @ Harbor Freight)
Build your hose by replacing one end with the fitting from the AC recharge hose, as shown in video. Hose clamp a barb between them, hook the other end up to your regulator.
PROCEDURE:
1. Start your engine
2. Open rear driver's side window and put the hose through (you can't change suspension height with door open--see Step 6 below)
3. Purge the air from the hose with nitrogen.
4. Hook the fitting up to the nipple on your Jeep's nitrogen tank (behind & under the rear seat. Nipple is on driver's side. It has a dust cover you'll need to remove. No tools necessary for this step.)
5. Set your regulator to 150 psi and allow the onboard reservoir to fill
6. Not sure if this is necessary, but I run through all suspension heights while the hose is connected.
7. Shut off your cylinder, unhook hose from Jeep, replace dust cap, and you're good to go!

Thanks for posting, great video. At this point over the years I've had my 2013 Jeep Grand Cherokee Overland into the dealerships about 4 times, each time they took a week or more to figure it out. About $4, 000.00 in repairs. Again now in 2023 the system is down in the front and will not activate the pump to raise. Doing the troubleshooting myself this time. If it looks like it will cost another fortune I will probably just put in T- Connections on the front and rear hoses with Schrader valves and raise it to desired heights depending on what I am doing with an air pump. Never again will I have a Quadra Lift, the Dealerships just make tons of money off repairing their own faulty system.

I feel your pain. I'm about $2400 in the hole, on my 5th compressor, and my Jeep has been at the dealership for more than three months collectively. I've taken it to multiple dealerships, they've enlisted the "help" of FCA, and still nobody has been able to fix it properly, or even find the problem. Now that I have the tools at home, I don't even sweat it anymore. Good luck brother 💪🏼

Hey where to I find a tank of nitrogen with the valve locally??

@krisdwight78 15 дней назад

So true man! I just got my 2015 overland back after 8 months with air suspension issues and the fronts are down again. Haven't even had it for a week and I spent like $4500

We have a 2011 GC Summit. It's getting old, 12 years. Our Quadra-lift suspension has been excellent. We put it in Park mode everytime we stop somwhere. I read of many issues but figers-crossed, we haven't had any. I have thought about emptying the nitrogen tank and maybe even draw it down with a Air Conditioning service Vacuum Pump. Then refiilling. Moisture in the system I would believe could cause the bags and struts to rot from the inside out? Love the video. Thanks.

@davidschaffer4884 8 месяцев назад

From the extensive research I've done, I get the sense that most QuadraLift systems are dependable and trouble-free like yours. But there are some out there that are complete lemons, and nearly impossible to diagnose (like mine). I understand the theory behind pumping down the whole system with a vacuum, but I personally wouldn't do it. Too many valves, connections, pliable parts (e.g. airbags) that are not designed for negative pressure. Some people suggest adding a sorbent to the system, but it's a closed system, so there shouldn't be any moisture in there to begin with. I also tend to think if it ain't broke...

@@davidschaffer4884 I'm sorry you have had so many issues with the suspension. Our time may be coming. We are worried more about the 5 7 engine. They have Cam and Lifter failures that can cost about $5000 to repair unless you DIY. I used to do lots of Mechanic work until someone broke my Back. Burst fractured L2. Now I can hardly bend enough to tie my shoes let alone lean over to tear down an Engine.

@Japplesnap 7 месяцев назад

Do not apply vacuum to the system. It's not designed for vacuum. You can simply evacuate it and refill it with high purity nitrogen and it will be fine

@Analyzer52 4 месяца назад

@davidschaffer4884 There is a lot of things that say this is not a closed system. The claim is that the system has an intake and filter on the passenger side and will pull in atmospheric air if there is not enough nitrogen in the tank.

@jamesmcneal9019 3 месяца назад

What kind of nitrogen did you use and how big of a tank??

@jerryabouelnasr2101 6 месяцев назад

I heard that the connection is proprietary to jeep. Appears this wasn’t the case on yours…

The same one you would use to refill the low side for your A/C R-134a refrigerant

Can I just use regular air ?

You can but it's not recommended due to moisture causing rust

@Japplesnap 7 месяцев назад

Did you delete my comment? I'll say it again--- the procedure outlined in this video is not the proper way to fill the air suspension tank. The AlfaOBD app has the capability to allow you to properly evacuate and refill the system exactly like a dealership scan tool.

@MrWurthit4660 5 месяцев назад

@Japplesnap how/where do you obtain the AlfaOBD app

@Japplesnap 5 месяцев назад

@@MrWurthit4660 It's an app. Get it on your phone if you have an Android. You can't get it with an iPhone.

@TvehX Месяц назад

That's fine, but ultimately the system only cares about the pressure in the tank, so if you haven't leaked down to atmospheric and injested water vapor, this isn't going to hurt anything. It's an air bottle, three valves, and some sensors.
